Triple-axis accelerometers tailored for consumer electronics apps

Austin, Tex.  Freescale Semiconductor has expanded its low-g triple-axis analog accelerometer product family with four new devices aimed at consumer electronics requirements that call for low-power consumption, advanced motion sensing and small form factor. The MMA7361L, MMA7368L, MMA7341L and MMA7331L sensors have tailored features designed to enable motion sensing in mobile phones, hard disk drives, media players, games and toys.

The MMA73xxL XYZ-axis analog accelerometers provide a self-test diagnostic feature that verifies the accelerometer is in working order at any time before or after it is implemented in design. The family offers a selectable 1.5g to 12g range to address various sensing functions such as fall, tilt, motion, positioning, shock and vibration for multi-functional applications.

Consumer designers will find the MMA73xxL accelerometers well-suited for use in cell phones and portable media devices to provide functions such as tilt scrolling, gaming control, tap to mute and freefall hard-disk-drive protection. In addition to enabling mobile platforms, the MMA73xxL devices also can be used in consumer applications that require wireless sensing such as enabling remote control LED lighting for home and industrial automation.

Development tools also are available for the MMA7361L, MMA7368L, MMA7341L and MMA7331L accelerometers.

Pricing: Suggested resale price starts at $2.71 for the accelerometers, in quantities of 10,000. The KIT3376MMA7361L, KIT3376MMA7368L, KIT3376MMA7341L and KIT3376MMA7331L development kits are available at a suggested resale price of $35.00 each. The ZSTAR2 kit (orderable tool number RD3473MMA7360L), which is the wireless triple-axis successor to the ZSTAR, is available at a suggested resale price of $99.00.
Availability: The accelerometers are available now.
